40 The ``rmr_get_src`` function will copy the *source*
41 information from the message to a buffer (dest) supplied by
42 the user. In an RMR message, the source is the sender's
43 information that is used for return to sender function calls,
44 and is generally the hostname and port in the form *name*.
45 The source might be an IP address port combination; the data
46 is populated by the sending process and the only requirement
47 is that it be capable of being used to start a TCP session
50 The maximum size allowed by RMR is 64 bytes (including the
51 nil string terminator), so the user must ensure that the
52 destination buffer given is at least 64 bytes.
58 On success, a pointer to the destination buffer is given as a
59 convenience to the user programme. On failure, a nil pointer
60 is returned and the value of errno is set.
66 If an error occurs, the value of the global variable
67 ``errno`` will be set to one of the following with the
